<p>Reports inconsistencies in overriding method signatures.</p>

<p><b>Example:</b></p>
<pre><code>
class Book:
    def add_title(self):
        pass


class Novel(Book):
    def add_title(self, text):
        pass
</code></pre>

<p>Parameters of the <code>add_title</code> method in the <code>Novel</code> class do not match the method
  signature specified in the <code>Book</code> class. As a fix, the IDE offers to apply the Change Signature
  refactoring.</p>
